Your answer should be 3a^2 + 5x + 9
A^3-19 should be the answer, good luck
Answer:
Below in bold.
Step-by-step explanation:
Area = 30 + 12x and area is also = to width * length so we need to look for factors of 30 + 12x.
30 + 12x = 6(5 + 2x)
So 6 and 5 + 2x is one possible answer.
3 and 10 + 4x is another.
12 and 2.5 + x is another.
If we multiply these pairs together we see that the result is
30 + 12x in each case.
12. Both sides of the equation are equal and if 18 is half of 36 then 6×2 will give you the value of X
I used the Old Change New method and I crossed multiplied.
The answer is about $498 (I rounded $497.895875)
